SIMH is the Computer History Simulation system. It consists of simulators for approximately 20 different computers, all written around a common user interface package and set of supporting libraries. SIMH can be used to simulate any computer system for which sufficient detail is available, but the focus to date has been on simulating computer systems of historic interest. 1.2 Why was SIMH written? Significant portions of the computing past are being irretrievably lost, as old systems are scrapped, documentation and software is thrown out, media become obsolete or unreadable, and inventors and pioneers die. SIMH was written as a vehicle to allow the computing past to be made accessible to a wider audience, for recreational and educational purposes. SIMH preserves historic computers as portable software that can be run on any modern system. SIMH also preserves representative software packages for these systems. With SIMH, anyone with a desktop computer can call up and run significant samples from the computing past, at any time. 1.3 What is the history of SIMH? The SIMH project started in 1993, at the suggestion of Larry Stewart of DEC. Its immediate purpose was to preserve the fading hardware and software record of early minicomputers. Since then, the project has been expanded to include other important systems, spanning the history of computing from the late 50's to the late 80's. SIMH's core design is based on an earlier simulation system called MIMIC. MIMIC was written in the late 1960's at Applied Data Research, by Mike McCarthy, Len Feshkens, and Bob Supnik. MIMIC was a mini- computer simulator that ran on the PDP-10. Its purpose was to facilitate the development and debugging of real-time embedded systems by using the PDP-10 timesharing environment for program development, instead of the limited facilities of the native minicomputer environments. Ironically, given SIMH's mission to preserve the computing record, all machine-readable copies of MIMIC have been lost. 1.4 Who writes and maintains SIMH? Many people have contributed, and continue to contribute, to SIMH. The full list of contributors can be found on the SIMH web site. Bob Supnik coordinates SIMH development. 1.5 How is SIMH licensed? SIMH is licensed under a modified X-Windows license. This license allows more or less unrestricted use of the sources and binaries. The license is included with the documentation and is also included in every source module. The software packages are available under various terms and conditions; see the documentation included with each software package. 1.6 How is SIMH distributed? SIMH is distributed in source form from GitHub in the form of a Zip archive (https://github.com/simh/simh/archive/master.zip) or by directly accessing the GitHub repository (https://github.com/simh/simh). For Windows users, pre-compiled binaries are also available (https://github.com/simh/Win32-Development-Binaries). 1.7 Which computer systems does SIMH simulate? SIMH simulates the following computer systems: Manufacturer Model Digital Equipment Corporation PDP-1, PDP-4, PDP-7, PDP-8, PDP-9, PDP-10, PDP-11, PDP-15, VAX-11/780, MicroVAX 3900, VAX-11/730, VAX-11/750, VAX-8600, MicroVAX I, MicroVAX II, rtVAX 1000 (Industrial VAX 620) Data General Corporation Nova, Eclipse IBM Corporation 1130, 1401, 1620, System 3, 7094 701, 704, 7010/1410, 7070/7074, 7080/702/705/7053, 7090/7094/709/704 GRI Corporation GRI-909 Honeywell Corporation H316/516 Hewlett Packard Corporation HP2116, HP2100, HP21MX, HP3000 Interdata Corporation 16b systems, 7/32, 8/32 Scientific Data Systems SDS-940, Sigma 32b MITS Altair 8080, Altair Z80 Royal-Mcbee LGP-30, LGP-21 Lincoln Labs TX-0 Manchester University SSEM (Small Scale Experimental Machine) Control Data Corporation CDC1700 Burroughs B5500 The documentation contains more details on supported models and peripherals. 1.8 Which host systems does SIMH run on?

Category 11 Breaches of confidentiality Date 1999-01-29 Keyword data leakage privacy confidentiality control Web Source, Vol, No. RISKS 20 18 The Canadian consumer-tracking service Air Miles inadvertently left 50,000 records of applicants for its loyalty program publicly accessible on their Web site for an undetermined length of time. The Web site was offline as of 21 January until the problem was fixed. Date 1999-02-03 Keyword data leakage Web script QA vulnerability confidentiality Source, Vol, No. WIRED via PointCast An error in the configuration or programming of the F. A. O. Schwarz Web site resulted paradoxically in weakening the security of transactions deliberately completed by FAX instead of through SSL. Customers who declined to send their credit-card numbers via SSL ended up having their personal details — address and so forth — stored in a Web page that could be accessed by anyone entering a URL with an appropriate (even if randomly chosen) numerical component. Date 1999-02-10 Keyword e-commerce credit card personal information password privacy Source, Vol, No. RISKS 20 20 Prof. Ross Anderson of Cambridge University analyzed requirements on the AMAZON.COM online bookstore for credit card number, password, and personal details such as phone number. He identified several risks: (1) merchant retention of credit card numbers poses a far higher risk of capture than of capture in transit; (2) adding a password increases the likelihood of compromise because so many naïve users choose bad passwords and then write them down; (3) even the British site for Amazon contravenes European rules on protecting consumer privacy; (3) such practices make it easier for banks to reject their clients' claims of fraudulent use of their credit-card numbers.

  • MICROSOFT WINDOWS Early Versions Main Articles: Windows 1.0
    MICROSOFT WINDOWS Early versions Main articles: Windows 1.0, Windows 2.0, and Windows 2.1x Windows 1.0, the first version, released in 1985 The history of Windows dates back to September 1981, when Chase Bishop, a computer scientist, designed the first model of an electronic device and project "Interface Manager" was started. It was announced in November 1983 (after the Apple Lisa, but before the Macintosh) under the name "Windows", but Windows 1.0 was not released until November 1985.[5] Windows 1.0 achieved little popularity and was to compete with Apple's own operating system. Windows 1.0 is not a complete operating system; rather, it extends MS-DOS. The shell of Windows 1.0 is a program known as the MS- DOS Executive. Components included Calculator, Calendar, Cardfile, Clipboard viewer, Clock, Control Panel, Notepad, Paint, Reversi, Terminal and Write. Windows 1.0 does not allow overlapping windows. Instead all windows are tiled. Only modal dialog boxes may appear over other windows. Windows 2.0 was released in December 1987 and was more popular than its predecessor. It features several improvements to the user interface and memory management.[citation needed] Windows 2.03 changed the OS from tiled windows to overlapping windows. The result of this change led to Apple Computer filing a suit against Microsoft alleging infringement on Apple's copyrights.[6][7] Windows 2.0 also introduced more sophisticated keyboard shortcuts and could make use of expanded memory. Windows 2.1 was released in two different versions: Windows/286 and Windows/386. Windows/386 uses the virtual 8086 mode of Intel 80386 to multitask several DOS programs and the paged memory model to emulate expanded memory using available extended memory.

  • Major System Files, and Their Purpose: Windows 9X –Specific Files • IO.SYS the Io.Sys File Is an MS-DOS and Windows 9X
    Major System Files, and their purpose: Windows 9x –specific files IO.SYS The io.sys file is an MS-DOS and Windows 9x hidden system file that is used to load the operating system each time the computer boots. The file is not editable using normal text editors. MSDOS.SYS The MSDOS.SYS file is a hidden system file created on the root of the boot drive. To edit this file, type edit msdos.sys. The PC boot environment can be changed by changing the file contents. Given below is a typicalMSDOS.SYS file: Below is a sample MSDOS.SYS File [Paths] WinDir=C:\WINDOWS WinBootDir=C:\WINDOWS HostWinBootDrv=C [Options] BootGUI=1 Network=1 BootMulti=1 ; ;The following lines are required for compatibility with other programs. ;Do not remove them (MSDOS.SYS needs to be >1024 bytes). AUTOEXEC.BAT An AUTOEXEC.BAT file contains DOS commands that are executed automatically when a PC boots. The file is usually located in the root directory of the hard drive of the computer. The AUTOEXEC.BAT file is used to set defaults and to run programs that should be executed during startup. Example: PROMPT $P$G Use the PROMPT command to alter the default DOS prompt. The above command makes the DOS prompt display the current path and drive, and is very useful. COMMAND.COM 1. It does: The file contains internal command set and error messages 2. Default Attributes: Nil 3. Is it required for OS Start up: YES 4. Responsible for displaying the command prompt in a DOS based computer.

  • Bill Gates' Original Dream When He Created Microsoft Was to Have
    Bill Gates’ original dream when he created Microsoft was to have “a computer on every desk and i n every home, all running Microsoft software.” Clearly, he accomplished that goal. Depending on whose statistics you want to believe, Windows has a market share in the high 80% - low 90% rang e. So, unless you run Linux or prefer Mac OS X, chances are you’re a Windows user. When it comes to desktop operating systems, your choices are really pretty narrow. You either run Windows, or you do some Unix-like OS. There are the 12,000 different Linux distributions. There’ s always FreeBSD if you prefer your Unix without a Finnish flavor. You could go the vendor route and run AIX or HP-UX. Sun has Solaris, and as much as you might want to, you can’t forget SCO. And of course, there’s always Mac OS X. Although it may sound like variety when it comes down to it, it’s still Windows vs. Unix. There are other options, or at least there USED to be. Here are a list of five of the best operating s ystems that you probably never used. OS/2 No discussion can be had of Microsoft alternatives without mentioning OS/2. Until Microsoft ship ped Windows 2000 Professional, OS/2 4.0 was probably my desktop OS of choice. For the purpos es of this section, I’m referring to OS/2 2.0 and later, not IBM and Microsoft’s ill fated OS/2 1.x s eries. IBM billed OS/2 as being a “Better DOS than DOS” and a “Better Windows than Windows”.
